I was bowhunting before dawn and the field in front of me was suddenly illuminated from an unknown source.

I was sitting in a tree stand, bowhunting for deer. It was still completely dark. The tree stand was approximately 50 yards from a cornfield. The whole field was suddenly completely illuminated. I then saw 2 small lights moving across the north side of the cornfield. After 2 to 3 minutes they came back across the field and disappeared. The field continued to be lit up for several more minutes. Then the light went out and it was completely dark again. At no time did I hear any type of sound and at no time did the light move.
